To all whom t may concern:

Be it known that we, RICHARD EISEN- TRAUT and FRIEDRICH VIELER, residing at Dillingen-Saar, Germany, have invented certain new and useful Improvements in Steam- Traps and we do hereby declare the following to be afull, clear, and exact description a weight secured on the upper part of the ofthe invention, such as will enable others said rocking-lever.

A weight parts hereinafter fully described and claimed. 37 is secured on the other end of the lever 37,

The air-valve 7 is provided with a stem 34 Fig. 2 and Fig. 3 are vertical sections taken having a beveled portion 33 at its lower end.
